(3)Astronomers, like early explorers who map Earth’s continents, are busy charting the spiral structure of our galaxy, the Milky Way Using infrared images from NASA’s Spitzer Space Telescope, scientists found that the Milky Way’s elegant spiral structure was dominated by two arms surrounding the ends of a central rod of stars Previously, it was thought that our galaxy had four major arms
(4)The annotated author’s concept presents a new perspective on the Milky Way You can see the galaxy’s two main arms, Scutum-Centaurus and Perseus, attached to the end of a thick central rod, and the two small arms, Norma and Sagittarius, now demoted, are less distinct and located between the main arms

(3)The main arms are the densest in both young and old stars
(4)consist of The small arms are usually filled with pockets of gas and star formation

(1)The artist’s concept is a radio telescope on Milky Way gas
(2)It also includes a new spiral arm called the Far-3 kilopasek arm, which was discovered through investigation This arm is shorter than the two main arms and lies along the galaxy’s bars
(3)Our sun is near a small part of the arm called the Orion arm, or Orion spurs, located between the Sagittarius arm and the Perseus arm
